FIELD OF THE DISCLOSURE

The present disclosure is generally directed toward modular bags and, in particular, toward various modular bag systems that utilize removable inserts.

BACKGROUND

A bag, such as a handbag or tote, is a bag that comes in a variety of sizes and holds various items. The modern origin of these bags began in Europe during the 17th and 18th centuries when people began to travel more frequently and by varying modes of transportation. A variety of bag sizes, shapes, and styles soon emerged for use during different occasions and circumstances. As the bag industry increased in size and complexity, the aesthetics and design of the bags increased in importance. Eventually, the bag industry developed into the industry we see today where the fashion and design of the bag are of great importance.

Bags also provide functionality in addition to fashionable design. Early bags were used to carry coins and currency as well as other items such as pipes, matches, and pocketknives. As the bag industry grew and as the complexity of the world at large increased, bags were purposed for a variety of applications. For example, modern bags are used to carry disparate items such as notebook computers and baby supplies. Due to this specialization of bags, the interior and exterior of bags began to include specialized features to accommodate the disparate items carried in bags. For example, bags today may include a specialized pocket or sleeve for a particular model of notebook computer or a specialized pocket or sleeve for baby diapers.

Another modern advent in the bag industry is skyrocketing prices for fashionable or luxury bags. Some fashion brands have had price increases of 50-60% in the past decade, and some fashion brands consistently increase prices up to 13% per annum. With bag prices at all-time highs, bag users are limited to fewer bags. Burgeoning fashion and luxury markets in China, India, and Brazil will ensure an upward pressure on bag prices for years to come.

As bags are specialized for carrying a wide variety of items and as bags continue to become more expensive, a particular problem has emerged. A typical bag user cannot buy a bag with a particular fashion or design for every specialized application. In other words, it is becoming more cost prohibitive to buy a bag for baby supplies, for professional items, for electronic equipment, for toiletries, for sports gear, etc. Further yet, bags that include features for a particular use may have a limited lifespan. A bag that has features specialized for baby supplies will only be useful as long as the user needs to carry those items. Therefore, there is a need for a bag that can provide a user with a particular fashion or design and that has specialized features that carry or secure a wide variety of items.

SUMMARY OF THE INVENTION

It is thus an aspect of embodiments of the present invention to provide a bag with a particular fashion or design that can be used in a wide variety of applications and uses. It is a further aspect of this invention to provide a bag with modular inserts that may be connected to the bag to provide application-specific functionality to the bag.

It is a further aspect of embodiments of the present invention to improve the utility of a fashionable bag by increasing the bag's longevity or usefulness. When user purchases a fashionable bag for a particular application, that application may not last indefinitely. As mentioned above, a fashionable bag that is specific to baby needs loses its utility when the baby grows up and there is no need for specialized features that carry diapers, formula, creams, change pads, etc. In embodiments of the present invention, a user can simply swap out the baby-specific inserts and replace them with other inserts such as inserts for a professional adult that can accommodate notebook or tablet computers, paper pads, pens, USB drives, etc. Further, the user can switch between various inserts during a day-to-day routine, not just when a bag specialized for a particular application entirely loses its utility.

It is another aspect of the present invention to provide multiple inserts so that insert combinations are available for a user. The interior of a bag may comprise multiple interior sides upon which a separate insert may be connected to each interior side. Using the baby example again, a multi-insert combination provides an advantage where baby products and other items are strategically placed within the multiple inserts such that a user may readily and easily access the products or items.

Another aspect of the present invention is to provide a bag that is easily cleaned. Many uses of a bag result in a bag that is dirty and messy. A bag directed towards baby needs may experience spilled snacks, formula, juice, milk, and other supplies. The modular design of embodiments of the present invention allows various inserts to be removed such that the bag may be thoroughly cleaned. Further, the bag and its various features, such as inserts and zippers, may be made from a water resistant or water proof material so that they may be readily washed. In a similar vein, features such as a waterproof lining may be incorporated into the inserts and their features to prevent the contents carried items from leaking out.

It is yet another aspect of the present invention to provide utility beyond fashionable bags. In the examples used thus far, a bag is fashionable and allows a user to switch inserts to transition between baby care, professional life, travel, crafts, fitness, etc. However, fashion is not only common denominator in the present invention. For example, a user may desire to purchase a bag because of its camouflage properties, yet also desire to use the camouflage bag in a variety of applications. In addition, there are varying types of camouflage for different environments. Before the present invention, if a user wanted multiple types of camouflage for use in multiple, specific applications, the user would need to purchase many bags. In contrast, in embodiments of the present invention the user can simply choose which camouflage bags and which specific applications are required, then mix and match the various modular components of the present invention. The same concept can extend to other utilities beyond fashion and camouflage such as durability for work use, waterproof qualities for underwater use, etc.

An aspect of the present invention is to provide a modular system that aids in the prevention of accidental injuries or the enhancement of general safety. A color-coding system for various components and features of a bag may help with injuries or safety. A user may want to utilize a bag to carry substances or devices that may be potentially harmful to the user or others. A color-coding scheme can help mitigate the risk of accidental exposure to a harmful substance, accidental injury from a device, or other ills. For example, a parent may want to carry prescription medication in his or her bag that has baby-specific inserts. A bag, insert, pocket, or other feature that is a solid color of warning such as red, will signal others to not disturb the contents of the feature. This is useful in the context of a baby-specific bag because even young children can associate colors with harm or ill consequences.

Embodiments of the present invention may include removable or modular inserts that are releasably attached to various locations on a bag. These inserts may come in a variety of shapes, but in one embodiment the inserts have a first major surface and a second major surface that interconnect to each other along a top edge, a bottom edge, and two side edges. In some embodiments, the inserts are disposed in the interior cavity of the bag, and the first major side is proximate to the interior surface of the bag, and the second major side faces the interior cavity of the bag. These inserts may comprise fastening features that allow the insert to attach to the bag. In some embodiments, the inserts are releasably attached to the bag such that the inserts may be freely attached and detached from the bag, which allows a user to quickly switch inserts in the bag depending on the user's particular needs.

Further, embodiments of the present invention may include removable or modular pockets that are releasably attached to various locations on a bag. Similar to the inserts, the pockets may be disposed in a variety of locations on the bag and the inserts, but in one embodiment, these pockets are disposed on the inserts. In some embodiments, the pockets are attached with more permanent means such as threaded stitching, but in other embodiments, the pockets are releasably attached to the inserts such that the user may mix and match various inserts and pocket to suit the user's particular needs.

In embodiments of the present invention, the inserts and the pockets may interface with one another to provide additional properties to the bag. The inserts may attach to one another at their respective side edges to provide more complete protection to the interior surface of the bag, and this configuration may also aid in providing more complete water proof or water resistance characteristics to the bag. The inserts themselves may also comprise extensions that extend from one or more edges of the inserts to interface with other components of the bag and provide even more protection, or in other cases, concealment.

An embodiment of the present invention is a modular bag that comprises an outer shell; and a first insert configured to be releasably attachable to the outer shell via a releasable mechanism.

Another embodiment of the present invention is a modular bag that comprises an outer shell; a first removable insert that is releasably attachable to an interior surface of the outer shell; and a second removable insert that is releasably attachable to at least one of the interior surface of the outer shell and the first removable insert.

A further embodiment of the present invention is a removable insert configured to interface with a bag interior, the removable insert comprising a first major surface, an opposing second major surface, a top edge connecting the first and second major surfaces, a bottom edge opposing the top edge and connecting the first and second major surfaces, a first side edge adjacent to the bottom edge and top edge, and a second side edge adjacent to the bottom edge and top edge and further opposite the first side edge, wherein the first major surface is configured to face toward the bag interior and the second major surface is configured to face toward a bag cavity, and wherein at least one of the first major surface, top edge, bottom edge, first side edge, and second side edge include a releasable mechanism that enables the removable insert to be removably attached to the bag interior.

The second rear insert pocket 284 includes a second pocket zipper 288 that provides access to the second rear insert pocket 284. The second pocket zipper 288 allows a user to securely store various items. Disposed on the front of the second rear insert pocket 284 is the fourth rear insert pocket 294, which is approximately 4″ wide and 2″ tall. The fourth rear insert pocket 294 may be comprised of an elastic material and allows a user to stow away small items such as keys.

The third rear insert pocket 292 is approximately 4″ wide and 6″ tall, and the third rear insert pocket 292 is designed to carry smaller electronic devices such as cell phones and Personal Digital Assistant devices.

FIG. 8 shows a left side insert 308 and a right side insert 320. The combined width 328 of the two inserts 308, 320 is approximately 17-19″, and the side insert height 332 is approximately 12-14″. For the embodiment depicted in FIG. 1, the combined side insert width 328 is approximately 17″, and the side insert height 322 is approximately 14″. For the embodiments depicted in FIGS. 2 and 3, the combined side insert width 328 is approximately 19″, and the side insert height 322 is approximately 12″. One skilled in the art will appreciate that these dimensions and others described herein are only exemplary, and other embodiments of the present invention may have various sizes and dimensions.

The left side insert 308 has a left insert fastener 312 that corresponds to the left interior fastener 228. In this embodiment of the present invention the left insert fastener 312 is the bottom portion of a zipper that is concealed by a 1-2″ flap that keeps the design of the bag clean. Likewise, the right side insert 320 has a right insert fastener 324 that corresponds to the right interior fastener 232, and in this embodiment, the right insert fastener 324 is also the bottom portion of a zipper that may be concealed by a 1-2″ flap.

In this embodiment, the left side insert 308 comprises a left side pocket 316, and the right side insert 320 comprises a right side pocket 326. Both side pockets 316, 320 are approximately 4.5″ wide and 9″ tall. Further, both side pockets 316, 320 are made from an elastic material and are designed to secure baby bottles, sippy cups, water bottles, juice bottles, and other containers.

The inserts 236, 276, 308, 324 described in FIGS. 6-8 and their features may be made from a variety of material in addition to the materials already described above. For example, it may be advantageous for an embodiment of the present invention to be washable. To meet this condition, the inserts 236, 276, 308, 324 and their features may be made from nylon or any other washable material. Other conditions and requirements may result in the inserts 236, 276, 308, 324 and their features being comprised from other materials.

Further the inserts 236, 276, 308, 324 and their features may be comprised of a number of colors or patterns. In one embodiment, the inserts 236, 276, 308, 324 and their features are the LENA by Cassandra™ print which has both chartreuse and black coloring. Beyond patterns and colors for the purposes of design and fashion, patterns and colors may also be used for color-coding the inserts 236, 276, 308, 324 or their features. For example, if the second rear insert pocket 284 contained a substance that was potentially harmful to children or even adults, a solid red coloring scheme would present a warning to others not to tamper with the contents of that particular pocket. This is also useful in the context of the Baby Insert configuration depicted in FIGS. 6-8 because children can associate colors with harm instead of a parent attempting to explain the specific nature of the potentially harmful substance to the child.

The various features of the inserts 236, 276, 308, 324 may be attached to the inserts 236, 276, 308, 324 in a variety of ways such that the bag is modular in nature. Using the front insert 236 as an example, the first front insert pocket 252, the second front insert pocket 256, and the third front insert pocket 260 may be attached to the front insert 236 by threaded stitching, Velcro, snaps, buttons, or any other form of attachment disclosed herein or commonly used in the bag industry. Likewise the fourth front insert pocket 264, the fifth front insert pocket 268, and the sixth front insert pocket 272 may be attached to the first front insert pocket, the second front insert pocket 256, and the third front insert pocket 260, respectively, by any of the means described herein.

The type of connection between the inserts 236, 276, 308, 324 and their various features may depend on the particular application of the user. For example, if a user intends to use the bag for a single application over an extended period of time, he or she may prefer the front insert pockets 252, 256, 260, 264, 268, 272 to be attached to the front insert 236 by threaded stitching or other more permanent means of attachment. Conversely, a user may use the bag for a variety of application over a short time period, and thus, the user will require the front insert pockets 252, 256, 260, 264, 268, 272 to be releasably attached to the front insert 236 by Velcro, snaps, buttons, or other semi-permanent means of attachment. One skilled in the art will appreciate that not all connections depicted in FIGS. 6-8 are necessarily identical. For example, the first front insert pocket 252 by be attached to the front insert 236 by threaded stitching, and the fourth front insert pocket 264 may be releasably attached to the first front insert pocket 252 by a snap fastener.

The inserts 236, 276, 308, 324 may interface with one another to provide a property or characteristic to the bag 100. For example in one embodiment of the present invention, the inserts 236, 276, 308, 324 may attach to one another at the edges of the inserts. The front insert 236 may comprise a releasably attachable means disposed on either of its side edges that are between its first and second major sides. The releaseably attachable means allow the front insert 236 to interface with similar releasably attachable means on the left insert 308 and right insert 320. Likewise, the rear insert 276 may interface with the left insert 308 and right insert 320.

In another embodiment, any of the inserts 236, 276, 308, 324 may comprise extensions that extend beyond the insert to interface with another component of the bag 100. The front insert 236 may comprise an extension that extends downward, then across the bottom surface of the interior cavity of the bag 100. The extension may then interface with the bottom edge of the rear insert 276. The interior surface of the bag 100 is often made from less durable material than the exterior surface of the bag 100, and this extension could protect the bottom surface of the interior cavity of the bag 100 if the user is going to subject the bag 100 to harsher use.

In yet another embodiment of the present invention, the inserts 236, 276, 308, 324 may be combined into a single insert that essentially lines the interior surface of the bag 100. This combined insert may attach to the interior surface of the bag 100 in any of the above-described ways. This embodiment presents several advantages. The combined insert prevent any wear on the interior surface of the bag 100, and in the same vein, the combined insert can provide more complete water proof or water resistant qualities such that any spills or liquids that contact the inside of the cavity formed by the combined insert will not affect the interior surface of the bag 100.

This embodiment also provides opportunity for concealment. Pockets or other features described herein may be disposed on the interior surface of the bag 100 to carry items that the user wishes to be concealed. Then, the user may attach a combined insert to the bag 100, and other features such as flaps may disguise the fact that there are pockets or other features underneath the combined insert. This aspect of the present invention may be useful to store away particularly valuable items against theft or damage. Beyond harms, this aspect may simply keep rarely-used items out of sight from the user.
